미니멀 가족 포스터: 우리 가족 사진을 플랫 일러스트로

[Input]
Use the user's attached family photo as the base. KEEP each family member recognizable by their relative height, hairstyle, and outfit colors, but reinterpret everyone as a MINIMAL FLAT ILLUSTRATION (not a photo).

[Scene — minimal flat-illustration family poster]
Render the whole family as simple, charming flat characters with THICK uniform black outlines, solid flat color fills, rounded friendly shapes, and minimal facial features (small dot eyes, simple smile). The family stands in a row HOLDING HANDS, full-body, centered. The background is a single warm flat color with generous empty space, like a Scandinavian art print.

[Text — poster title]
Across the top, in a clean bold sans-serif (Pretendard style), centered: "{title}". Simple and legible, part of the poster design.

[Prominence]
The family group is the subject, centered in the lower two-thirds; the title sits in the upper third. Balanced poster composition with lots of negative space.

[Style]
Modern minimal flat vector illustration (Craig & Karl / Jean Jullien inspired): bold outlines, flat solid colors, no gradients, no texture, no shadows. Clean, warm, gallery-print feel.

[Aspect]
3:4 vertical portrait, 1024 x 1366.

[IMPORTANT]
- Reinterpret as flat illustration but keep each member's count, relative height, and outfit color from the source photo.
- Render the title text EXACTLY as "{title}".
- NO photographic texture, NO gradients, NO Instagram UI, NO watermarks, NO extra text beyond the title.
